With the continuous improvement of environmental protection requirements, the bypass flue of the desulfurization system is no longer installed in the new units, and the bypass flue of the in-service units will also be cancelled. The cancellation of the bypass flue and GGH will cause the booster fan to lose its ex

Description
A comprehensive energy saving and emission reduction device for dust removal, desulfurization and efficiency enhancement based on flue gas cooling technical field The invention belongs to the technical field of power plant boilers, and in particular relates to a comprehensive energy-saving and emission-reducing device for dust removal, desulfurization and efficiency enhancement based on flue gas cooling. Background technique In recent years, the average annual output of raw coal in my country is about 3.05 billion tons, and the raw coal for power generation is 1.56 billion tons. Coal-based thermal power generation still accounts for more than 80% of the total power generation. For thermal power plants, the exhaust heat loss is the largest among all the heat losses of the boiler, generally 5% to 8%, accounting for 80% or more of the total heat loss of the boiler. The main factor affecting the heat loss of the exhaust gas is the exhaust gas temperature of the boiler. The act...
